ABSTRACT:
An electrically heated kiln having a ventilation system in accordance with the present invention includes a hinged upper wall, a lower wall, and side walls forming a firing chamber. The kiln further includes an upper ventilation aperture formed in the upper wall and a lower ventilation aperture formed in the lower wall. A duct connects the lower aperture with the outside environment. An exhaust fan, coupled to the duct, draws incoming air into the kiln through the upper aperture, downwardly through the kiln, and outwardly through the lower aperture into the duct to be expelled outside. The downward movement of the air and kiln gases causes turbulence near the upper portion of the kiln to create a more uniform temperature within the kiln. The apertures are sized and the draw rate is selected so as to provide proper ventilation of the kiln. The draw rate is preferably between 8% and 45% of the kiln volume per minute when measured at room temperature through the lower aperture. Both the upper and lower apertures may be formed of a plurality of openings.
